I need help in drawing the intersection between 2 cylinders.
2D Isometric Draw, Cylinder Intersection (AutoCAD 2018)
Post your dwg please.

Back in the old days, you project the length of the lines I showed in colors, then use a french curve to draw that intersecting line.
With autocad today, best way is to draw 3d.

The simplest way would be to create a 3D model. If this is done, you can create each view you want with nearly "one click".
If you need urgently a 2D solution, you have to draw a lot of construction lines first. I show it in the attached dwg for the visible line of the side view. You have to repeat this for the invisible lines (of the holes) too.
The construction of the Iso view will be still more elaborate. Tell us first if you really need it.

Of course, the best way would be to make a 3D model and have AutoCAD determine the intersection. But, if you want to work only in 2D using only the 2D isometric drawing you could use the following approach.
1. make copies of the front blue arc (ellipse) so that one is at the middle of the object (red), another copy is displaced a know amount from the center (I used 10 for the green arc) and another (20 for the cyan arc).
2. copy the red arc to the extreme edge of the vertical cylinder by using the ends of the magenta line yielding the magenta arc.
Now draw lines at 30° from the center and displaced by 10 and 20.
Drawing vertical lines from the ends of these lines to their respective arcs (actually ellipses) define points at the intersection of the two cylinders. The yellow spline is the intersection.
